If it is a definite IP address it is server. If it is a site which distributes
definite IP addresses (and pool in the name is hint) it is probably pool. What
happens with a pool address as I understand it, is that a query to a pool
address delivers back something like three actual addresses of ntp servers,
which is what chrony uses as server address to get time info from. So, if you
have a pool then if you look at chrony while it is running ( using chronyc and
the sources directive) you will will see something like 3 actual server
addresses which are used by chrony.

I want to programmatically configure chrony, but I don't know if the given address is
server or pool. The addess is something like »10.0.100.100« or »0.de.pool.ntp.org«. This
worked well in centos 7 with ntp package. With centos 8 and chrony, I need to decide
whether to use »server« or »pool« directive in /etc/chrony.conf. As I understand the man
page, none of these two directives is good for both cases.
Thanks, Jože
